Seismic

All ConeTec cones and data acquisition systems are built seismic ready. The addition of geophones in the CPTu body enables the collection of seismic wave data, and the calculation of shear (Vs) and compressional (Vp) wave velocities during the cone penetration test.

Shear waves have particle motion perpendicular to the direction of travel. A normally loaded beam is struck horizontally on each side to create polarized shear waves at regular depth increments. Manual, automatic, and vibratory sources are available depending on the application and rig used.

Compression waves have particle motion parallel to the direction of travel. A vertical impact source is typically used as the source.
